Types

Jdbc

@ExperimentalCoroutinesApi

@ExperimentalRiverApi

class Jdbc(connectionPoolSize: Int = 10, connectionFactory: () -> Connection)

Row

typealias Row = Map<String, Any?>

Functions

batchUpdate

@ExperimentalRiverApi

@ExperimentalCoroutinesApi

fun <T> Jdbc.batchUpdate(sql: String, upstream: Flow<T>, concurrency: Int = 1, groupStrategy: GroupStrategy = TimeWindow(100, 250.milliseconds), prepare: suspend PreparedStatement.(T) -> Unit = {}): Flow<Int>

Executes a batch update for the given SQL statement using the provided upstream Flow as input. The batch update is performed in chunks, as specified by the groupStrategy parameter, and can be executed concurrently using the specified concurrency level.

query

@ExperimentalRiverApi

@ExperimentalCoroutinesApi

fun Jdbc.query(sql: String, fetchSize: Int = 100, prepare: suspend PreparedStatement.() -> Unit = {}): Flow<Row>

Executes a query for the given SQL statement using the provided fetchSize as a result set fetch size.

singleUpdate

@ExperimentalRiverApi

@ExperimentalCoroutinesApi

fun Jdbc.singleUpdate(sql: String, prepare: suspend PreparedStatement.() -> Unit = {}): Flow<Int>

Executes a single SQL update using a JDBC connection.

@ExperimentalRiverApi

@ExperimentalCoroutinesApi

fun <T> Jdbc.singleUpdate(sql: String, upstream: Flow<T>, concurrency: Int = 1, prepare: suspend PreparedStatement.(T) -> Unit = {}): Flow<Int>

Executes a single SQL update using a JDBC connection for each item in the upstream flow.

typedQuery

@ExperimentalRiverApi

@ExperimentalCoroutinesApi

inline fun <T : Any> Jdbc.typedQuery(sql: String, fetchSize: Int = 100): Flow<T>

@ExperimentalRiverApi

@ExperimentalCoroutinesApi

inline fun <T : Any> Jdbc.typedQuery(sql: String, fetchSize: Int = 100, crossinline prepare: suspend PreparedStatement.() -> Unit): Flow<T>

Executes a typed query for the given SQL statement using the provided fetchSize as a result set fetch size. The resulting Flow emits objects of type T, which must have a primary constructor and whose parameters are matched with the columns of the result set.
